Class Polygon(VMobject)

Polygon is a general purpose closed continuous line constructor for a 3D point array. Polygon can be used to generate polygon of any type from a given point set. Polygon can also be used as a dummy polygon constructor for other defined polygon. Crossed polygon is also accepted.

Example

Code

# folder/file: tut/manim_mobject_polygon_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.geometry import Polygon
from manimlib.animation.creation import ShowCreation

class manim_mobject_polygon_001a(Scene): 
   def construct(self):
      poly = Polygon((0,0,0),(1,1,0),(2,-1.2,0),(3,0,0),(2,-1,0),(1,-1,0),stroke_width=15,color="#88FF00",fill_color="#FFFF00",fill_opacity=1)
      self.play(ShowCreation(poly),run_time=2)
      self.play(ShowCreation(Polygon((-6.5,3,0),(-5,4,0),(-2,-1.2,0))),run_time=2)
      self.play(ShowCreation(Polygon((-5.5,3,0),(-4,4,0),stroke_width=50)),run_time=2)
      self.play(ShowCreation(Polygon((5.5,3,0),stroke_width=50)),run_time=2)
